You know the drill: You’ve got an image on your puter. You print it.
It’s either really small, or it’s big enough, but really blocky and nasty looking.
So what gives?

If you’ve read any reviews recently about phones, tablets, and other gizmos, you’ve probably come across a lot of talk of PPI (Pixels Per Inch) and “Retina” screens.

But hang on a minute… Just what do these numbers mean?
Does it really matter that much?
